Just picked it up this afternoon. Fantastic game. Considering the cost ( works out around 70p) it really is worth quite a bit more. Like someone has already dais, there's XBLA games out there that are not half as good as this.
I'd been waiting for a decent top down racer for a while then 2 come out at once (this and MotorStorm RC)

And TTK, I like how you made the NeoGaf thread as ridiculous and as overblown as possible - still I way to go to beat that Assassins Creed thread though

Nah, that's about standard for GAF official threads! I really like them, too, it's nice seeing someone so enthusiastic about a game they're happy to do that, and I think it makes other people more partial to give games a try if they see how much the poster loves it. I know I've tried games based on threads I've clicked on just because of how much the OP seems to care about it.

The guy who made the second post in the thread actually started the LRS thread before I did, and that was his opening post. Which one makes you want to try it!

Oh man, the chase cam in this is amazing. It's like a totally different game! It's pretty hard to see what's coming up so the first few laps are insane, but once you learn whatever track you're on so you know what's coming, it's wonderful. It swings around a bit and drifting around corners just feels awesome.

It's not a replacement for the top-down camera, but it is really good.

I had a go with the different camera types and apart from the standard isometric one or maybe the other top down one I can safely say the others are absolutely bloody awful. Had my first 20-odd lap race last night and it was terrifying towards the end as I realised my second place was slowly bwing wound in as the red bar gradually increased each time I scraped a corner. Great stuff!
